[PATCH net-next v2 0/2] Add support for ICSSG on AM64x EVM

[PATCH net-next v2 0/2] Add support for ICSSG on AM64x EVM

[MD Danish Anwar]

This series adds support for ICSSG driver on AM64x EVM.

First patch of the series adds compatible for AM64x EVM in icssg-prueth
dt binding. Second patch adds support for AM64x compatible in the ICSSG 
driver.

This series addresses comments on [v1] (which was posted as RFC).
This series is based on the latest net-next/main. This series has no
dependency.

Changes from v1 to v2:
*) Made the compatible list in patch 1 alphanumerically ordered as asked
   by Krzysztof.
*) Dropped the RFC tag.
*) Added RB tags of Andrew and Roger.

[v1] https://lore.kernel.org/all/20230830113724.1228624-1-danishanwar@ti.com/

Thanks and Regards,
Md Danish Anwar
